If so inclined, Koko could have probably name-dropped by sign language the famous friends she made during her 46 years.

The Bay Area gorilla who became a worldwide celebrity for her ability to communicate through American sign language counted Robin Williams, Betty White and Mr. Rogers among her celebrity friends. Koko died in her sleep Tuesday at the Gorilla Foundation headquarters in Woodside.

During a 2001 visit by Williams, Koko instructed the comedian to “chase” and “tickle” her. She also picked his pocket, and took his glasses and wore them as her own.

“We shared something extraordinary — laughter,” Williams said of his visit. “Koko understands spoken English and uses over a thousand signs to share her feelings and thoughts about daily events — life, love, even death. It was awesome and unforgettable.”

Williams could be seen in a video cracking up as he and Koko engaged in a tickling match. Koko’s caretaker told Williams she might have recognized him from a video of one his movies. At one point, Koko signed that she loved Williams.

Williams described his time with Koko as “mind-altering.”

Koko was also said to be a fan of “Golden Girls,” and she befriended one its stars, Betty White, in 2004.

“To look in the eyes of a 300-pound gorilla and have her tell what she’s thinking is truly humbling,” said the longtime animal rights activist.

“She’s right into my eyes, and I’m right into hers. There’s a connection, like an invisible connection between you that at that moment nothing else around you exists. You’re just into the moment because it’s someplace you’ve never been before. It’s a new country,” White also said.

Koko’s guest appearance on “Mister Rogers’ Neighborhood” was recently included in the documentary “Won’t You Be My Neighbor?”
